Abstract: Provided is a polycarbonate resin composition comprising: a polycarbonate resin comprising a constituent unit having an alicyclic hydrocarbon site where a carbonate group is linked to two carbon atoms that constitute a ring and are adjacent to each other; and one or two or more compounds selected from the group consisting of a compound having an amide bond, a sulfur compound, and a phosphite ester compound, wherein weight-average molecular weight Mw of the polycarbonate resin measured by size-exclusion chromatography using polystyrene as a standard sample is 50,000 or larger and 500,000 or smaller.

Abstract: A polycarbonate resin comprising a structural unit represented by the following formula (1), wherein weight-average molecular weight Mw measured by size-exclusion chromatography using polymethyl methacrylate as a standard sample is 50,000 or larger and 500,000 or smaller:

Abstract: Provided are a microorganism that produces a diamine compound and a method of producing a diamine compound. The genetically modified microorganism expresses an enzyme involved in synthesis of a diamine compound, in which the diamine compound is represented by Formula: H2N—R—NH2 (wherein, R is a chain or cyclic organic group comprised of one or more atoms selected from the group consisting of C, H, O, N, and S), and the genetically modified microorganism is modified to reduce an activity of an alcohol dehydrogenase compared to a non-reduced strain.
